Super Audio CD (SACD) is a high-resolution, read-only optical audio disc format developed by Sony and Philips Electronics, the same companies that created the Compact Disc and the S/PDIF specification used in digital audio cables. SACD is designed to provide high-resolution audio in both stereo and surround sound modes. SACDs use an audio format called DSD in addition to an optional CD-compatible layer using traditional PCM.

Introduced in 1999, SACD has not been accepted by the mainstream market, but continues to thrive in the audiophile community with new SACD recordings and players being made.

Overview

SACD is a disc of identical physical dimensions to a standard compact disc; the density of the disc is the same as a DVD and it encodes audio using a process known as Direct Stream Digital. The SACD sampling rate is 2.8224 MHz and the resolution is one bit. A stereo SACD recording can stream data at an uncompressed rate of 5.6 Mbps, four times the rate for Red Book CD stereo audio.[1] SACD recordings can have a wider frequency and dynamic range than conventional CDs.

There are three types of SACDs:[1]
